4-digit 7-segment led display thermometer using 1N4148 diode

You can made a cheap thermometer using few components: clone Arduino board (in my case, I use Arduino Nano board with uC ATmega 168, but work with Arduino nano with ATmega328, Arduino Uno, leonardo, etc), a 1N4148 diode, 4-digit 7-segment led display with common cathode or common anode (just few changes in sketch), an breadboard and some wires.
Schematic is very simple:
